Which option is most appropriate if you want to protect access to your computer temporarily while keeping your user session open?
Answer
Lock
Explanation
### Why this is right
Lock protects access while preserving the user's session. That makes it appropriate when you step away temporarily but expect to return to the same session.
### The concept
Power options differ in whether they end a session or change the computer's power state. Logging off ends the user session, while shutting down and restarting close the current session as part of turning the computer off or starting it again.
### The other options
- **B. Log off**: Ends the user's session, so it is not the temporary access restriction described.
- **C. Shut down**: Powers off the computer rather than keeping the session open.
- **D. Restart**: Starts the computer again and closes the current session.
### Watch out
Locking a computer is not the same as logging off.
### Remember
Use Lock to restrict access without ending the session.
